Stumbling over nursing jargon (5)
I believe the answer is:
lingo
'jargon' is the definition.
(synonyms)
'stumbling over nursing' is the wordplay.
'nursing' indicates a hidden word (the answer is held or nursed by the clue).
'LINGO' is hidden in the letters of 'stumbling over'.
(Other definitions for lingo that I've seen before include "means to communicate" , "speech" , "Log in (anag.)" , "local dialect" , "Jargon, language (colloq.)" .)
